In the days before sprawling residential subdivisions, children at play could often be seen traipsing through meadows or climbing trees. Now it’s more common to find boys and girls being shuttled from school to computer to soccer practice as part of a fast-paced schedule that leaves little time for daydreaming or exploring nature. The result, says journalist Richard Louv, is “nature-deficit disorder.” Louv coined this term, which is not a medical diagnosis, to call attention to the absence of nature in children’s lives. In his newest book, Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder (Algonquin Books), he ties the lack of time spent in nature to everything from childhood obesity to psychological disorders.
